Upgrade your on-the-go audio with the premium Astrum BT230 2-in-1 Bluetooth 5.3 Transceiver. Built into a sleek 15g zinc alloy body, this high-performance audio adapter features dual TX/RX modes, an integrated LED status display, dual independent volume controls, a built-in microphone, and an ultra-fast 45-minute USB-C charge time.
The Astrum BT230 2-in-1 Bluetooth 5.3 Transceiver is a premium, ultra-compact wireless audio adapter housed in a durable 15g zinc alloy chassis. Engineered with a built-in 3.5mm AUX plug, this standalone hardware solution allows you to seamlessly toggle between Transmit (TX) and Receive (RX) modes, instantly upgrading non-Bluetooth hardware without requiring apps, drivers, or software operating systems.
In Transmit (TX) Mode, the unit plugs directly into older TVs, laptops, gym treadmills, or airplane entertainment systems to broadcast high-fidelity audio wirelessly to your favorite Bluetooth headphones or portable speakers. Switching to Receive (RX) Mode allows you to stream wireless music directly from your smartphone or tablet to legacy car stereos, home theater amplifiers, or wired headphones. An integrated microphone handles crystal-clear hands-free calls seamlessly while operating in RX mode.
Equipped with an intuitive integrated LED display, the BT230 provides real-time visibility into active modes, pairing statuses, and battery health levels. Onboard independent tactile volume buttons allow you to fine-tune your audio levels directly on the transceiver without dampening your host source volume. Driven by an efficient 120mAh rechargeable battery, it charges fully in just 45 minutes via USB-C to yield up to 5.4 hours of RX playback, 2 hours of TX playback, or a massive 6-month standby capacity.
